In addition to the included widget types, you can add the capacity for more complex widgets to your Protégé-2000 project by loading special projects that extend the possible widgets. Protégé-2000 includes the following projects, in the newspaper folder, that allow you to extend the types of widget you can use:
a table project, which allows you to display information stored as a function of two classes in tabular format
a diagram project, which allows you to display relational information in the form of a diagram or graph.
To use these widgets, you must not only include the related project, but you must add other information to your project and, in the case of tables, make sure your project is actually constructed to support the widget. The additional work required, however, allows you to create an interface which conveys complex information in a visual and immediate way. See the tutorial for more information.
